Mutations that occur in skin or lung cells have little effect on the evolution of a species because mutations in these cells 1
usually lead to the death of the organism
2
cannot be passed on to offspring
3
are usually beneficial to the organism
4
lead to more serious mutations in offspring

i think the answer would be d

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
